The failure phenomenon of the spring machine safety valve mainly has the following situations: 1. The safety valve cannot be normally switched;
2. The safety valve cannot be opened as usual;
3. The valve has air leakage, no elastic force or a tight sealing surface.
Measures taken in response to these phenomena:
1. Always check and adjust or replace the spring to clean the surface of the dirt, such as air leakage grinding or replacement (calibrated according to technical standards);
2. Use the check calibration and the disassembly check to follow the instructions to troubleshoot.
